An easy way to import/export Flatpaks would be really convenient. On Windows, I can easily move around software using a usb drive to a computer that may not be connected to the internet. I'd have no clue how to do that on Linux aside from AppImages
But due to fragmentation etc. I'd guess that such portable flatpaks would be huge, as they'd need to carry all dependencies in case the other end is missing some
Ocarina of Time. I didn't grow up with the older games but I'm having fun so far. I'll play the other titles afterward
